What is Olivia Benson's son's name?

Olivia Benson's son is named Noah Porter-Benson, also written as Noah Porter Benson.

Benson became Noah's court-appointed custodial guardian at the end of SVU's 15th season. Noah was an orphaned baby whose biological mother, Ellie Porter, had been trafficked and murdered. Benson initially received custody for a one-year trial period, with the possibility of applying for adoption afterward.

The adoption storyline became one of the show's major long-running personal arcs. Noah experienced serious health problems, and Benson had to balance motherhood with the demands of leading the Special Victims Unit. His biological father, John “Johnny D” Drake, later attempted to claim custody, creating another legal and emotional crisis for Benson.

Noah's surname connects him to both his birth family and his adoptive mother: Porter comes from Ellie Porter, while Benson reflects Olivia's role as his adoptive parent. He is sometimes confused with Calvin Arliss, a boy Benson temporarily fostered and served as legal guardian for earlier in the series, but Calvin is not her son.
